Ruby on Rails is a popular rapid development web framework that allows web designers and developers to implement fully featured dynamic web applications using the Ruby programming language. This guide describes the required process for deploying Ruby on Rails with Passenger and the nginx web server on Ubuntu 10.04 (Lucid).
Before you begin installing and configuring the components described in this guide, please make sure you've followed our instructions for setting your hostname. Issue the following commands to make sure it is set properly:
hostname hostname -f
The first command should show your short hostname, and the second should show your fully qualified domain name (FQDN).
Issue the following command to reload your system's package repositories and ensure that all installed programs are up to date:
apt-get update apt-get upgrade
Use the following command to install system packages required for using Ruby, building Ruby modules, and running Rails applications:
apt-get install wget build-essential ruby1.8 ruby1.8-dev irb1.8 rdoc1.8 zlib1g-dev libopenssl-ruby1.8 libopenssl-ruby libzlib-ruby libssl-dev libpcre3-dev
Issue the following sequence of commands to install the latest version of Ruby Gems for managing ruby-specific packages:
cd /opt/ wget http://production.cf.rubygems.org/rubygems/rubygems-1.5.1.tgz tar -zxvf rubygems-1.5.1.tgz cd /opt/rubygems-1.5.1/ ruby setup.rb ln -s /usr/bin/gem1.8 /usr/bin/gem
In the future you can issue the following command to update your version of gem to the latest release:
gem update --system
Create symbolic links to the installed version of Ruby:
ln -s /usr/bin/ruby1.8 /usr/bin/ruby ln -s /usr/bin/irb1.8 /usr/bin/irb
Install the rake and rack gems:
gem install rake rack ln -s /var/lib/gems/1.8/bin/rake /usr/bin/
Finally, install the version of Ruby On Rails that your application requires. Issue one the following commands for the version you need:
gem install rails --version 2.1.2 gem install rails --version 2.2.2 gem install rails --version 2.3.5 gem install rails --version 3.0.4
If you are unsure of the version you require, you can install the latest version with the following command:
gem install rails
Additionally, the application you deploy will likely have additional dependencies. Install these dependencies before proceeding.
Proceed to the Phusion Passenger site and locate the link for the current source code tarball. Download it as follows (substitute the link for the current version):
cd /opt wget http://rubyforge.org/frs/download.php/73563/passenger-3.0.1.tar.gz tar xzvf passenger-3.0.1.tar.gz
Run the Phusion Passenger installer for Nginx:
cd /opt/passenger-3.0.1/bin ./passenger-install-nginx-module
You'll be greeted by the Phusion Passenger nginx installer program. Press "Enter" to continue with the installation.
The installation process will begin an interactive session that will guide you through the process of building Phusion Passenger. When prompted for the nginx installation method, we recommend you choose "1" for both options to allow the installer to automatically download, compile, and install nginx for you. Unless you have specific needs that would necessitate passing custom options to nginx at compile time, this is the safest way to proceed. Accept the default installation location for nginx.
Please do not remove the Passenger files from opt after the installation. They need to stay in place or your installation will not function correctly.
Nginx is now installed in /opt/nginx, but there are no "init" scripts to control this process. Issue the following sequence of commands to download a script, move it to the proper directory, set the proper permissions and set system startup links:
cd /opt wget -O init-deb.sh http://library.linode.com/assets/601-init-deb.sh mv /opt/init-deb.sh /etc/init.d/nginx chmod +x /etc/init.d/nginx /usr/sbin/update-rc.d -f nginx defaults
You can now start, stop, and restart Nginx just like any other server daemon. For example, to start the server, issue the following command:
The configuration file for Nginx is located at /opt/nginx/conf/nginx.conf. This is the file you'll need to edit to add support for your Rails applications. A default server is already configured in this file, and it also contains examples for alternate virtual host and SSL configurations.
If your application uses MySQL, install the database server by following our MySQL on Ubuntu 10.04 (Lucid) guide. Once it's installed and configured properly, issue the following commands:
apt-get install libmysqlclient15-dev libmysql-ruby gem install mysql --no-rdoc --no-ri -- --with-mysql-dir=/usr/bin --with-mysql-lib=/usr/lib/mysql --with-mysql-include=/usr/include/mysql
